Package uk.ac.starlink.ttools.task

Class SkyDensityMap

  • All Implemented Interfaces:
    uk.ac.starlink.task.Task
    public class SkyDensityMap
extends SingleMapperTask
    Calculates sky density maps and outputs them as tables.

    The current implementation has the limitation that the same combiner has to be used for all aggregated quantities. If you want to calculate for instance the median of some quantities and the mean of others, you're out of luck. It's hard to work out what the parameters would look like to do it more generally.
